Search Engine Optimisation (SEO) is built on three pillars: content, technical performance, and authority.
While content and technical factors make your website accessible and informative, authority is earned largely through link building.
Put simply, link building is the practice of acquiring hyperlinks from other websites back to yours.
These backlinks act as signals of trust, helping search engines determine which websites deserve top positions.
If you’re just starting out, the idea of building links might sound overwhelming. But don’t worry-this guide will break it down into clear, beginner-friendly steps.
And if you’d rather have experts handle it, you can always rely on professional link building services that specialize in safe, sustainable strategies.
What is link building in SEO?
Link building is the process of getting other websites to hyperlink back to your site. A hyperlink (or link) allows users to move from one webpage to another, but for search engines, it serves as a way to evaluate credibility.
Think of it like academic research: a research paper with more citations from respected sources is considered more trustworthy. Similarly, a website with high-quality backlinks is seen by Google as more authoritative.
- A link from a respected industry publication tells Google you’re a thought leader.
- A link from a local business directory signals your credibility in a geographic area.
- A link from a trusted blog confirms that your content is valuable and shareable.
The goal isn’t to get the most links but to earn the right links-those that are relevant, authoritative, and organic.
Why link building matters for SEO
Google’s algorithm has evolved over the years, but backlinks remain one of the top three ranking factors. Without them, your site is like an island: even if you publish great content, it may remain invisible.
Benefits of link building:
- Improved rankings-Backlinks boost your domain authority, helping you rank higher.
- Faster indexing-Search bots discover your site more quickly via links.
- Referral traffic – Links bring visitors directly from other sites.
- Brand credibility – Earning a backlink from an authoritative site builds trust.
- Networking opportunities – Outreach often leads to partnerships, collaborations, or guest posting opportunities.
Example: A small SaaS startup publishes a free tool that calculates marketing ROI. A leading digital marketing blog includes it in their resources page, sending thousands of referral visitors and boosting the startup’s rankings on competitive keywords.
How backlinks work
When Google evaluates backlinks, it considers multiple dimensions:
- Authority of the linking domain-Links from The New York Times or HubSpot are far more impactful than links from unknown blogs.
- Relevance-A fitness website linking to a gym equipment brand carries more weight than a cooking blog linking to the same site.
- Anchor text-If the link text says “best SEO tools,” Google understands that the destination page is likely about SEO tools.
- Context and placement-A link placed naturally within a blog post is more valuable than one hidden in a footer.
- Follow vs nofollow – Dofollow links pass authority. No-follow links don’t directly pass ranking signals, but they still diversify your link profile and drive traffic.
Types of backlinks every beginner should know
Backlinks come in different forms. Understanding them helps you prioritise efforts:
- Editorial links– earned naturally when your content is cited as a source.
- Guest post links – Acquired by contributing content to relevant sites.
- Resource links-inclusion in “best of” lists or curated collections.
- Broken link replacements-Offering your content as a substitute for a dead link.
- Directory citations-Useful for local SEO when listed in niche or local directories.
- Social mentions-Often nofollow, but good for visibility.
- Internal links-Managed within your own site to distribute authority.
Pro tip: Prioritise editorial and resource links, as they carry the most SEO weight.
When to work with a link-building company
Not every business can manage outreach campaigns, content creation, and relationship building internally. That’s when hiring a link building company makes sense.
When outsourcing is valuable:
- You need links from authoritative sites in competitive niches.
- You lack an in-house SEO team.
- You want consistent monthly link acquisition.
- You need penalty recovery after a Google update.
A reputable company will provide transparent reports, white-hat practices, and measurable ROI. Avoid agencies that promise hundreds of links overnight-this is often a red flag for spam tactics.
